Title: Methane-rich gas process
IPC: C07C1/02
Filed: 1974-12-23
Abstract: A methane-rich gas stream is produced by catalytic methanation of synthesis gas feed comprising H2 and CO. When the mole % CO in the synthesis gas feed to the methanator is greater than 10 mole %, and the mole ratio H2/CO is in the range of greater than 1.0 to 3, by adjusting the mole % CO2 in the synthesis gas feed to the methanator to a value in the range of about 0.5 to 20, and the mole ratio H2/CO2 in the range of about 2 to 60 and preferably less than 3.9 it was unexpectedly found that a product gas is produced having a gross heating value which is greater than that which is obtained from a dry CO2-free methanator feed gas.

Patent ES-436944-A1 (ES)
Title: Sealing surface gauge
IPC: G01R1/067
Filed: 1975-04-24
Abstract: Apparatus and method for inspection of the sealing surface of a glass container. A glass container, having a finish portion with an annular rim or sealing surface, is rotated A light its vertical axis at an inspection station. Alight source focuses a thin line of light across the rim. A light sensor receives a reflection of this light from the rim, thus giving a normal light level signal. A defect in the rim causes a rise or fall in this normal light level signal. The signal caused by a defect is frequency filtered, with the normal light level signal being removed in the process, to give individual signals for different types of defects. These individual signals are then compared with pre-selected defect level signals and a defective container signal is generated if the pre-selected levels are exceeded.
Patent ES-437556-A1 (ES)
Title: Oscillator circuit
IPC: H01L21/331
Filed: 1975-05-09
Abstract: An oscillator circuit is provided which employs a single active element. In particular, the circuit utilizes a novel four-terminal semiconductor device which is able to act as a transistor with three of its terminals and, in case of use as the transistor, has the emitter-grounded current amplification factor hFE controllable with a voltage at its fourth terminal. When the novel four-terminal semiconductor device is connected so as to operate as an emitter-grounded transistor, voltage changes at its output terminal, which corresponds to the collector of the transistor, is the same in phase as voltage changes at its fourth terminal. This fact is utilized in the present invention to cause oscillation by the generative feedback from the output terminal to the fourth terminal.

Title: Telephone line battery boost circuit
IPC: H04Q3/42
Filed: 1977-01-26
Abstract: Transmission and signaling range of a telephone transmission line is extended by controllably inserting boost potentials into the line to series aid an applied central office battery.
